Just came from the alignment shop and I need to have the caster adjusted. It is currently at 4.5deg while running 265/75/16 tires, basically a 32" tire. My research suggests it should be about 6deg and that the low number is contributing to the "wandering" and tracking issues on the highway.

Anyone know where I can get the cam bolts and washers? Quadratic only has them for the rear UCAs.

NAPA sells them. i had to look them up myself and show the guy that worked them, who by the way was the owner or that particular store, how to find it. they may tell you it is something they dont carry casue they never have seen them. here is the part number just to make it easier #NCP 2643693

Great. So, next question, what is the best way to go about measuring the caster once the cam bolts are installed? I've searched the "end all be all alignment thread", but am not finding a good "how-to". Advice on this?

another alignment from the same shop as before. you'll need to reset toe after resetting caster because the angle of the knuckles changes slightly. with cam-bolts, they only get you ~1.5° caster max in either direction, so just max out the cam toward the front the vehicle to effectively "lengthen" the lower control arms. That should put you about 5.5-5.8° if you were at 4.5° before.

i've tried several tricks to measures caster on two different axle housings...the socket on the upper ball joint, the u-joint, the lower C like Gary2 described...and nothing has given me repeatable results. By repeatable, I mean I take the angle finder off and put it back on 10 minutes later or 10 days later, and don't get the same result - and none of them are the same as what the laser alignment rack at Firestone said. However, the u-joint has been the most linear delta...meaning u-joint says X°, and the alignment rack says Y°...so if I move it by +1°, I can measure at home and figure X+1°, and know with fair certainty the alignment rack will say Y+1°.

That's why I bought the Lifetime Alignment from Firestone, and when I want to know my alignment specs, I drive over there when they're not busy. Takes 20 minutes, I don't have to get dirty, and they give me a cool print-out. I've been in over 8 times in the past few years...

Unltd, that's exactly what I needed. The ones I saw on fleabay said they maxed at 1.5deg, so my assumption was that maxed in one way, or the other and given a 4.5 deg starting point, I'd either be at 3, or 6. Six would be probably perfect. Would 1.5 deg significantly change the pinion angle?

And, I bought the 1-year alignment from Kauffman...just to get the caster sorted.

Thks

you'll be fine on pinion angle, no problem.
